I just got a pair of ue6000 for $70 on Black Friday. I believe the price will yoyo a little. I am pleasantly surprised by how decent it sounds. A little hump on the bass but otherwise sounds pretty smooth. The best volume is mid volume. That's where the range is at its smoothest. Any louder and the bass overwhelms the rest to me. The noise cancellation feature is not really good but it's an option at least. I just listen to them passively. No need batteries, which are included By the way.
